Application [July [22, 1955, a Serial No, 523,654 "1 Claim. (Cl.214-653) This invention relates .to industrial elevating trucks of therfork lift :type used for picking up loads transporting loads atelevated levels and stacking the loads in a selected manner, and moreparticularly to an attachment for 'such .trucks particularly adapted for.handling large paper rolls.

It is the principal ,object of tthis invention :torprovide an attachmentof the character indicated above for handlingtpaper rolls which may bereadily installed with a minimum of modification oftthe :truck structureand which wi ll eflectively and safely grip large rolls of paper so asto transport the same without damage thereto, .from one place toanother, stack the rolls in a prescribed manner, and remove therollsfrom the stacks. 1 The above and other objects are attained byemployingthis invention'which embodies among its features, an attachmentfor handling paper rolls for :use with an -industrial elevating truck ofthe type having spaced upstanding'elevatorguides and an elevating meansassociated with the guides, the attachment comprising an upstandingelevator mounted on the guides for vertical movement therealong andoperatively connected to the elevating means, paper roll supportingrollers mounted on the elevator for movement toward and away from each.otherto grip paper rolls therebetween whenmoved toward each other and-to release rolls whcnmovedaway from each other, and means on theelevator and operatively connected to-the rollers to move them towardand away from-each other.

*Other objects and advantages will become apparent from .a considerationof the following detailed description, formingthe specification, and:taken in conjunction with the accompanying drawings, wherein:

Figure 1 is a fragmentary side elevational :view ofythe forward portionof an industrial elevating xtruck showing an attachment embodying thisinvention installed thereon; t

Figure 2 is a front elevational view thereof;

Figure 3 is an enlargedcross sectional view taken substantially along'line 3-43 of Figure ,2 and looking in the direction of the arrows;

Figure 4 is an enlarged cross sectional view through one of the rollerstaken substantially along line 4T4 of Fi u ,Figure Sis an enlarged crosssectional view taken along line .555 of Figure 4 and looking in thedirection of the arrows; and t Figure 6 is .an end elevational view of astackof paper rolls showing the manner in which the paper rollsupporting rollers maybe associated with the paper rolls in the stack.

With continued reference to the drawings, the forward portion of anindustrial elevating truck of the fork lift type, generally indicated10, has a pair of spaced, vertical elevator guides 12 at the front endthereof and between the front steerable wheels 14 of the truck. Thetruck has a conventional elevating means, generally indicated at 16,which is shown as of the hydraulically Patented Dec. 25 1956 operatedtype, and which is associated with the elevator guides.

The illustrated attachment embodying this invention isgenerallyindicated'at 18, and comprises an upstanding frame -20,ofrectangular form. The frame 20 has spaced parallel sideplates 22, avertical bottom plate 24 extending therebetween and connected to plates22 at their rear edges and an angleiron top bar 26 connected at itsopposite :to the :top ends of the side plates 22 and extendingttherebetween.

As :showndn Figure 3, an intermediate vertical plate 28 extends betweenthe side plates with its lower longitudinal edge engaged with the upperedge of the bottom plate 24, and is secured thereto by any suitablemeans.

A vertical plate 30 extends between the sideplates 22 and between thelower edge of the vertical flange 25 of the top bar '26 and the upperedge of the intermediate plate28tand has side flanges 32 extendingperpendicularly andtrearward lytherefrom toward the guides 12 atoppos'ite .endsuof :the support plate 30. Vertically spacedpairst-ofzupper .and' lowerwheels 34 and 35 arerot atably mounted\ontheouter'sides of the side flanges 32 and ride in-the-channels of theelevator guides 12. 'Theelevating means 16 is operatively connected tothe frame 20 adjacentthe 'lowertend thereof and to the bottom plate 24,as ;at.j3q6, :so :thattupon operation of the elevating means 16,thefram'e '20 ;will be raised or lowered. through theQperationofaconveniently disposedtoperating handle '38 on the truck '10.

vA pair of :Lshaped arms, generally indicated at 40 and 142 respectivelyare mounted on the frame 20 for movement crosswise of the frame and aremounted on vertically spaced :transverse guide rods 44 and 45 extendingbetween the side plates and passing through the vertical portionstls ofthe arms .40-and 42; As shown in Figure $4, the horizontally extendingportion 50 of each 10f the;arrns 1,40 and 42 projects forwardly. Tubularrollers 52 are ibored longitudinally to rotatably engage on thehorizontal portions 50. Anti-friction bearings '56 and 358 areinterposed between the roller 52 and the horizontal portion of each armadjacent opposite ends of the roller {to permit free rotation of theroller about the horizontalportions '50. 'It will be noted that thebores 54 of zthe :rollers 52 are provided with annular recesses 60311C162 adjacent opposite ends thereof in which the bearings56tand'5'8.are seated. Also, the portion 59, as shownjin Figure4, is :reducedtindiameter from a point adjacent to the vertical portion 48 to a pointadjacent to its free end so as to provide a stop shoulder 64 againstwhich :theantil-friction"bearing 56 is engaged against endwise movementand maintained in its recess 60.

At the free ends of the horizontal portions 50, are bearingstop washers66 secured to the free end of the horizontallportion bya nut 68 bearingthereagainst and threadedly received upon a reduced diameter stud 70.This .was'her 3.66 bears against one endof the anti-friction bearing 58to prevent endwise movement thereof and to maintain the bearingr5'8 inits recess 62.

Means :are provided on the frarne 20 for moving the arms 40 and :42 andconsequently the rollers 52, crosswise of the frame 20 toward and awayfrom each other whereby 18. large roll 72 of paper may be gripped ibe- 340. A hydraulic fluid conducting line 80 leads from a source ofhydraulic pressure commonly associated with the truck to the end of thecylinder remote from the end secured upon theside plate 22 and,selectively operable valve handle 82 is mounted at a convenient locationon the truck 10. A second hydraulic fluid conducting line 84 is alsooperatively associated with the source of hydraulic fluid pressure (notshown) normally associated with the truck 10 and leads to the oppositeend of the hydraulic cylinder 74, so as to be in communication with theinterior thereof. The line 84 is selectively controllable by aconveniently disposed valve handle 86 mounted on the truck 10 adjacentthe handle 82. Hence, by selective operation of the handles 82 and 86,the arm 40 may be moved transversely of the frame along the guide rods44 and 46.

Similarly, a lower horizontal hydraulic cylinder 88 has one end thereofsecured to the side plate 22 opposite to the side plate on which thecylinder 74 is mounted and extends perpendicularly therefrom toward theopposite side of the frame 20. The operating piston rod 90 of thecylinder 88 projects longitudinally therefrom and has its free endsecured to the upstanding or vertical portion 48 t toward each other andthereby lift the paper roll 72. It

will be noted that the rollers can accomplish this since they are freeto rotate about their longitudinal axes without causing damage to thepaper rolls therebeneath. When the rollers 52 have been separated to theextent that the paper roll 72 is cradled in the space therebetween andsupported on the rollers, the elevating mechanism of the truck can beactuated to lift the paper roll 72 from the stack and remove ittherefrom. Thereafter the paper roll 72 can be transported to any otherdesired location.

Also, as shown in Figure 6, where it is desired to stack paper rolls 72,the endmost paper roll 72" of the stack is placed upon the floor 100 orother similar supporting surface, in the manner hereinbefore set forthand the rollers 52 withdrawn by moving the truck rearwardly so that thepaper roll will be deposited at the location desired. Subsequent paperrolls 72 may then be placed by continued operation of the truck' and 10and the frame 20 and with the rollers on the arms 40 and 42 to completethe positioning of the other paper rolls.

In placing subsequent layers of paper rolls 72 upon a lower layer, itwill be noted that the rollers 72 may be withdrawn from the stackthrough the spaces between upper rolls and lower rolls in the stack.

While there is shown and described the preferred embodiment of theinvention, it is to be understood that the structure is susceptible tochange and modification with- I in the practicability of the inventionand therefore should upon the side plate 22. Thus, the cylinders 74 and88 may be simultaneously operated by selective operation of the handle82. The end of the cylinder 88 remote from the end having the connectionwith the hose 94 is interconnected into the line 84 by a flexible hose98 which is in communication at its opposite ends with the line 84through a suitable fitting and with the interior of the cylinder 88adjacent its end secured to the side plate 22 at its other end.Therefore, by actuation of the handle 86, the arms 40 and 42 may bemoved simultaneously in the opposite directions.

In operation, the truck 10 having been moved to a location at which itis desired to pick up a roll 72 of paper, and to transport the roll toanother location, and the frame 20 being in a depressed position, thearms 40 and 42 are moved away from each other so that the rollersthereon will straddle opposite longitudinal sides of the roll. Thehydraulic cylinders 74 and 88 are then actuated by means of the valvehandles to move toward each other and into contact with the oppositesides of the paper roll adjacent the floor or other surface upon whichthe paper roll rests. As soon as the rollers 52 make contact withopposite sides of the paper roll to be lifted, the elevating mechanism16 can be actuated and the paper roll lifted to the desired height alongthe elevator guides 12. The paper roll can then be transported to thedesired location, the elevator means actuated to lower the frame 20, andthe rollers 52 separated to deposit the roll at the desired location.

As shown in Figure 6, if it is desired to remove a paper roll 72 fromthe top of a stack of paper rolls, the rollers 52 are brought into closeside by side relation and elevated to the required height so that uponforward movement of the truck, the rollers will move into the spacesbetween the bottom of the top roll 72'. The rollers are then moved belimited only by the scope of the claim appended hereto.

What is claimed is:

In a lift truck, a truck body having a forward end, a pair of laterallyspaced vertical guides fixed on said forward end, elevating means onsaid body extending forwardly therefrom, a vertical frame in front ofand extending between said guides and operatively connected to saidelevating means for vertical movement along said vguides, said framehaving laterally spaced vertical side plates, upper and lower guideengaging means on said side plates supportably engaging said guides, apair of L- shaped arms having vertical portions and horizontal portionsextending forwardly from said vertical portions, upper and lower guiderods in said frame extending between and secured to said side plates,said vertical arm portions being slidably supported on said guide rodsfor movement therealong, a pair of horizontal hydraulic cylinders eachfixed at one end thereof to a related frame side plate and having apiston rod extending from its other end and secured to the verticalportion of one of said arms, and hydraulic actuating means severallyconnected to the hydraulic cylinders and operable to move said armsindividually crosswise of the frame and toward and away from each other,said horizontal portions of the arms having rotatable tubularcylindrical rollers journaled longitudinally thereon.
